User Wallet
One wallet unifying top DeFi protocols with automated payments and secure delegation
The Underscore User Wallet is a smart contract wallet that unifies access to top DeFi protocols through a single address. Execute complex multi-protocol strategies in one transaction. Delegate operations to AI agents and trusted operators within strict boundaries. Automate payments while funds earn yield. Move millions between your wallets instantly.
Built on Base L2, your wallet combines institutional-grade security with the flexibility to capture opportunities 24/7 — whether you're actively managing or sound asleep.
At its core, Underscore provides four key components:
Unified Protocol Access: Direct integration with top DeFi protocols through standardized adapters
Delegation System: Managers who can execute strategies within defined boundaries
Security Layers: Time-locks, whitelists, and granular permissions protecting every operation
One Wallet, Every Protocol
Underscore connects to DeFi protocols through standardized adapters called "Legos". Each Lego provides a consistent interface for protocol-specific operations, enabling atomic multi-protocol transactions with optimized gas usage.
Your wallet is future-proof: When new DeFi protocols launch or existing ones add features, they're automatically available to your wallet through new Lego integrations. No need to migrate funds, deploy a new wallet, or update anything — your existing Underscore wallet instantly gains access to every new protocol the moment its Lego is deployed.
Yield & Lending Protocols
Integrated protocols: Morpho, Moonwell, Aave, Euler, Fluid, Compound, plus specialized protocols like Avantis, ExtraFi, and more
Capabilities:
Deposit assets to earn yield
Withdraw funds with automatic unwinding
Track yields and calculate profits
Claim protocol rewards
Rebalance between protocols
Trading & DEX Integration
Integrated DEXs: Aerodrome, Uniswap, Curve
Capabilities:
Swap tokens with smart routing (up to 5 hops)
Add/remove liquidity with automatic ratio calculation
Support for both standard (uni v2) and concentrated liquidity (uni v3+)
Manage NFT positions and adjust ranges
Debt Management
Integrated protocol: Ripe Protocol
Ripe Protocol is Underscore's borrowing partner, letting you access liquidity without selling your assets. The key advantage: Underscore Earn Vaults are accepted as collateral. This means your assets can be earning AI-optimized yield while you borrow against them — you're not choosing between yield and liquidity, you get both.
How It Works:
Deposit Collateral: Lock assets in Ripe Protocol — including Underscore Earn Vault tokens
Borrow Against It: Take a loan in GREEN (stablecoin) or yield-bearing sGREEN
Keep Earning: If using Vault tokens as collateral, your underlying assets continue earning optimized yield
Repay Anytime: Pay back principal + interest on your schedule
Reclaim Collateral: Withdraw your assets once debt is cleared
Why This Matters:
Traditional borrowing forces a choice: either earn yield OR use assets as collateral. With Underscore + Ripe:
Deposit into an Earn Vault (AI optimizes your yield)
Use your vault tokens as collateral on Ripe
Borrow GREEN/sGREEN for liquidity needs
Your collateral keeps earning the whole time
Capabilities:
Deposit any supported asset as collateral
Use Underscore Earn Vault tokens as productive collateral
Borrow GREEN (stablecoin) or sGREEN (yield-bearing stablecoin)
Repay debt with any accepted token
Earn and claim RIPE rewards on debt positions
Manager Permissions:
Manage Debt: Add/remove collateral, borrow, repay
Managers cannot withdraw borrowed funds to external addresses
All operations respect standard manager limits
Why Borrow?
Access liquidity without selling appreciating assets
Keep earning yield on your collateral
Tax efficiency — loans aren't taxable events
Bridge short-term cash flow needs
Asset Transformations
Capabilities:
ETH ↔ WETH conversion with zero slippage
Mint and redeem receipt tokens (like stETH)
Handle delayed redemptions
Automatic format conversion for protocol requirements
Rewards & Incentives
Capabilities:
Batch claim rewards across all protocols in one transaction
Auto-compound rewards into productive positions
Track lifetime earnings across protocols
Batch Operations: Multiple Actions, One Transaction
Underscore's architecture allows complex multi-step operations to execute atomically in a single transaction. This provides significant gas savings and eliminates the risk of partial execution.
Examples of Batch Operations
Yield Rebalancing:
Complex Position Entry:
Portfolio Rebalancing:
Swaps: Trade Any Token
When you swap tokens through your Underscore wallet, the system finds the best route across integrated DEXes.
How Swaps Work
Multi-hop routing example:
Slippage Protection
Every swap includes slippage protection — you specify the minimum amount you'll accept. If market conditions change and you'd receive less, the transaction reverts.
Wallet default: Configurable per swap
Manager limit: Managers have maximum slippage caps (e.g., 1% max)
Fail-safe: Transactions revert rather than execute at bad prices
Swap Fees
Underscore charges 0.25% on swaps. This is in addition to any DEX fees (which go to liquidity providers).
Manager Swap Controls
When managers execute swaps, additional controls apply:
Maximum slippage percentage
Maximum swaps per period
Minimum USD value per swap
Asset restrictions (which tokens can be swapped)
Liquidity Provision: Earn From Trading Fees
Your Underscore wallet lets you provide liquidity to decentralized exchanges and earn a share of trading fees. This is one of the most powerful DeFi strategies — your assets work for you by facilitating trades for others.
How It Works
When you provide liquidity, you deposit a pair of tokens (like USDC and ETH) into a trading pool. Traders swap between these tokens and pay fees, which you earn proportionally to your share of the pool.
Basic Example:
Two Types of Liquidity
Simple Liquidity (Uniswap V2 style)
Deposit equal value of two tokens
Earn fees across all price ranges
Receive LP tokens representing your share
Supported on: Aerodrome Classic, Uniswap V2, Curve
Concentrated Liquidity (Uniswap V3 style)
Choose specific price ranges for your liquidity
Higher fees when price is in your range
More capital efficient but requires monitoring
Receive an NFT position (not fungible tokens)
Supported on: Aerodrome Slipstream, Uniswap V3
Manager Permissions for LP
Managers can handle liquidity operations with the Manage Liquidity permission:
Add liquidity to approved pools
Remove liquidity when rebalancing
Subject to all standard manager limits
Risks to Understand
Impermanent Loss: If token prices diverge significantly, you may have less value than if you held the tokens separately. This loss only becomes "permanent" when you withdraw.
Smart Contract Risk: LP positions exist within DEX smart contracts. Underscore integrates only with established, audited protocols.
Other Wallet Features
Eject Mode: Emergency Lockdown
If you suspect your wallet is compromised or need to restrict activity immediately, activate eject mode to lock down operations:
When Active:
Only transfers and ETH/WETH conversions allowed
No yield, swap, debt, or liquidity operations permitted
Only wallet owner can perform any actions
All managers are blocked from operating
Use Case:
Eject mode provides a panic button for emergencies — restrict first, investigate later.
Managers: Delegated Operations
Managers are authorized operators — human or AI — who execute actions within your defined boundaries. They can trade, optimize yields, and manage payments, but cannot withdraw to external addresses or exceed your limits.
Use cases:
24/7 yield optimization by AI agents
CFO handling vendor and contractor payments
Professional traders managing portions of portfolio
Automated debt position management
Family members with emergency access
Payees: Your Circle of Trust
Payees form your verified payment network — addresses that can only receive what you've pre-approved. Your funds earn yield until payment time, then transfer automatically. Only you can add addresses to this circle.
Use cases:
Employee salaries paid from yield-earning funds
Automated vendor and contractor payments
Subscription services with pull payment capability
Family allowances with monthly limits
Cheques: Digital Cheques with Control
Digital cheques bring the control of paper cheques to crypto — write payments that recipients cash on their schedule, cancel anytime before they do. Large amounts get automatic security delays. Your funds keep earning yield until payment.
Use cases:
Contractor payments you can cancel if work isn't delivered
Large transfers with built-in review time
Social payments like splitting lunch ($30 to a friend)
One-time vendor invoices with payment flexibility
Any payment where you need an "undo" option
Whitelist: Unlimited Trust
The whitelist breaks the emergency glass on your security — addresses that get unlimited transfers with no delays or limits. Time-locked additions protect against compromise, while instant removal maintains control.
Use cases:
Hardware wallet for emergency fund access
Corporate treasury requiring immediate consolidation
Multi-wallet strategies for risk distribution
Gnosis Safe for recovery if you lose access
Architecture Comparison
Multiple interfaces and logins
Single unified interface
Manual token approvals per protocol
Pre-configured protocol access
External transfers between wallets
Internal routing, no transfers
Manual yield tracking
Automatic profit calculation
Limited automation options
Full delegation capabilities
Separate security per wallet
Unified security model
Frequently Asked Questions
🔐 Security & Control
Is this a self-custody wallet? Yes, absolutely. You maintain complete control of your private keys and assets. Underscore provides the smart contract infrastructure, but only you can authorize transactions.
What happens if Underscore disappears? Your funds remain safe and accessible. The smart contracts are immutable and don't depend on Underscore's servers. You could interact with your wallet directly through BaseScan or any other interface.
Can I migrate to a new wallet? Yes. The protocol includes a migration system that lets you move funds and copy your configuration (managers, payees, whitelist) to a new Underscore wallet. Useful if you want access to new features or need to restructure your setup.
💰 Costs & Fees
What are the fees?
Swap fees: 0.25% on token swaps
External reward claims: 20% when claiming protocol rewards (MORPHO, WELL, etc.)
No fees on: Transfers, idle funds, deposits, debt operations, liquidity provision, or ETH/WETH wrapping
See Protocol Economics for details on how fees work and where they go.
Technical Setup
